Answer:
6x -3x^4
Step-by-step explanation:
Eliminate parentheses. Since the multiplying coefficient is +1, the parentheses can simply be dropped:
= 3x +2x^4 +3x -5x^4
Add like terms (ones with the same exponent on the variable).
= 3x +3x +2x^4 -5x^4 . . . . . . . group like terms together
= (3+3)x +(2-5)x^4
= 6x -3x^4
Answer:
4
Step-by-step explanation:
Answer:
5/4,2.5,3.7,4.75,5.5,6,28,29
Step-by-step explanation:
Question 1:Use the Pythagorean theorem.
If

, then the angle is acute.
If

, then the angle is right.
If

, then the angle is obtuse.






Thus, the angle is acute.
Question 2:Take the square root of the area to get the side length.

That's the side length. Since we have a 45-45-90 right triangle if we divide the square across its diagonal, we just multiply the side length by the square root of 2 in order to get the diagonal length.


Your answer is 20 m. Hope this helps! :)
